The phrase itself is ordinary everyday English, which is part of why this clip travels so easily online. Short reaction sounds built around a single recognisable phrase are widely shared on soundboards and in short-form video, where creators need an instant reply that needs no explanation. This version is under a second long, so it fits neatly into edits, stitches and meme replies without slowing the pace. Its staying power comes from versatility: the same two words can sound helpful, confident or gently sarcastic depending on the setup, making it useful long after a specific trend has faded.
